There are plenty of cute surprises in this lift-the-flap book that takes readers on a search to answer the titular question. Beside the query, “In this chair?” flipping a chair-shaped flap reveals a teddy bear and the refrain, “But where’s my sweetie pie?” An owl, frog, butterfly, and mouse await behind later flaps, culminating in a mirrored surface under a heart-shaped locket on the final spread: “There you are! Hello, sweetie pie!” The gentle buildup and “starring you” finish will likely prompt rereading. Up to age 3. (Jan.)
